Stepladder Technique

The stepladder technique (Rogelberg et al. 1992) is related to the modified Delphi in which face-to-face meetings are reintroduced, and member input is physically and logically cumulative. The process consists of N-l steps for a group with N members. Initially, a core group is formed by two members who work together on the assigned problem. Then, a third member is added to the group and presents his or her individual ideas to the core group for discussion, evaluation, and incorporation into the group consciousness. This process continues, adding one member at a time, until all group members have been included, all voices have been heard in turn, and the final group product is the cumulative contribution of all members. This is analogous to the cumulative Delphi (Schmoldt and Bradshaw 1989).
